Texture sampler in vertex shader? - OpenGL - Khronos Forums

WebA Geometry Shader (GS) is a Shader program written in GLSL that governs the processing of Primitives. Geometry shaders reside between the Vertex Shaders (or the optional Tessellation stage) and the fixed-function Vertex Post-Processing stage. A geometry shader is optional and does not have to be used. WebAdd this line in your fragment shader: gl_FragColor = vec4 (texture2D (Sampler, TextureCoordOut).xyz, 0.5); You should see some half transparency texture.
